| abstract |
The present invention relates to the technical field of inorganic pigments containing a product formed in situ by the double and / or multi reaction between a calcium carbonate and the reaction product or products of said carbonate with one or more H3O + ion donors moderately strong to and the reaction product or products of said carbonate with CO2 gas formed in situ and / or from an external feed, and at least one aluminum silicate and / or at least one synthetic silica and / or at least one silicate of calcium and / or at least one silicate of a monovalent salt such as sodium silicate and / or potassium silicate and / or lithium silicate, and / or at least one aluminum hydroxide and / or at least one a sodium and / or potassium aluminate containing less than 0.1% by weight of a monovalent salt silicate such as sodium, potassium or lithium silicate or mixtures thereof, relative to the dry weight of sodium carbonate, calcium, having a pH greater than 7.5 m at 20 ° C, and their uses in paper applications such as mass loading and / or coating of paper and more particularly printing paper, including offset printing, or digital printing such as printing by ink jet and / or laser. |
